Designing a Random Number Generator

- Designing a Random Number Generator Introduction Random Number Generator is a computational routine or a physical device that produces numbers which don’t have any pattern in them. Although using computational algorithms involves adding pattern to the resulting sequence of numbers. We focussed on generating uniformly distributed random numbers between (0,1) since the same distribution can be used to get numbers from different ranges. We all know that LCG is well known method for giving a sequence of randomized numbers using linear equation but it still has some issues....   [tags: computational routine, physical device]

Polls: Random Representative Sampling

- Having a large sample size in a survey does not assure accurate statistics. What really matters is the sample diversity. For example: you wanted to find out how many of your workmates watch football, it would be foolish to only survey the men in your office and assume that the statistic applies for all the company’s employees. In order to get accurate statistics, you would have to expand the survey to include the female employees and the workers in other company offices.

Measuring Random Appraisal Error in Commercial Real Estate

Thus, appraisal error is virtually unavoidable. Investors need reasonable estimates of value when buying, selling, or retaining commercial property, so an unknown amount of appraisal error adds uncertainty to the decision-making process....   [tags: essays research papers]

Linear Feedback Shift Registers

- Abstract: Linear Feedback Shift Registers (LFSRs) are considered powerful methods for generating pseudo-random bits in cryptography algorithm applications. In this paper it is shown that the linear dependencies in the generated random bit sequences can be controlled by adding a chaotic logistic map to the LFSR’s systems. The structure of the LFSR’s output sequence in combination with a chaotic map is analyzed and proved to have at least as much uniformity than the corresponding set for the linear components individually....   [tags: Computers, Cryptography]

The Effect of Different Types of Organized Lists on Word Recall

- The present study aimed to measure the effect of different types of organized lists on recall. Participants were randomly assigned into two groups and was presented with either a list of words organized Alphabetically (N=10) under the words corresponding letters or words organized in a Schedule (N=11), categorized under ellipses labeled with parts of a day-"Morning", "Afternoon", and "Evening" . Each list contained the same 90 words sans the organization of the list. Participants in both groups studied their respective list and recalled as many words as they could remember by writing them down afterwards in both trials under a restricted period of time....   [tags: categorical, alphabetical list, organization]

The Growth Rate of Males and Females

- The Growth Rate of Males and Females The purpose of this investigation of data handling is to investigate the rate of growth of males and females. The male sand females are pupils of the Mayfield high school in the North of England. I obtained the data from the Internet, of the pupils: Names, gender, year group, age, height, weight and I.Q. I sorted the data, to which I only needed the pupils year group, gender, height and weight. To investigate the data, I am going to need to create a random sample of pupils equally from year group and gender, down from 713 pupils because we only need years 7, 9, and 11, to just 300 pupils....   [tags: Papers]

Mandatory Drug Testing in High School Helps Prevent Drug Abuse

- “The only way to have a drug free school is to follow the successful program of the military and workplace”. This is stated by Rep. John E. Peterson in 2005. In today’s volatile times, drug use is becoming more casual in high schools around the country. Many schools are having to face this struggle against drug use. Thus, I affirm that Resolved: Drug testing of high school extracurricular activity participants is justified.To aid clarification in this round, I now present the following definitions asdefined by the Webster Dictionary in 2005:Extracurricular activity: not following or related to the curriculum, outside of one’s duties....   [tags: Drug Abuse, Substance Abuse]

History Of Monte Carlo Method

- It could be argued that current physics research could be divided into three areas - theoretical, experimental and computational. Numerical approach, in which systems are mimicked as accurately as possible using a computer or in which computer models are set up to provide well - behaved experimental systems are increasingly providing a bridge between theory and experiment, for instance; the Monte Carlo method (MC) and the molecular-dynamics method (MD). In Monte Carlo method the exact dynamical behavior of a system is replaced by a stochastic process, whereas the MD methods are based on a simpler principle and consists of solving a system of Newton's equations for an N-body system....   [tags: essays research papers]

On the other hand, a calibration error in the steel tape itselfâ€"an incorrect spacing of the markingsâ€"will produce a bias in one direction....   [tags: Physics]

Two main types of errors have been identified: Random sampling errors and Non-random sampling errors. The first derives from how well the sample selected represent the population being studied while the latter represents all types of error that may occur from sources other than sampling. Since non-sampling error is very broad it has been divided into response errors and non-response errors....   [tags: marketing research, Malhotra, Briks & Wills]

The length of backoff period is determined by the following equation Backoff Time= random () * 1 Slot Time....   [tags: contention-based, transmission, reservation-based,]
